Abstract
The effects of reclaimed asphalt pavement (RAP) content and cement content on the strength and durability of recycled aggregate base materials typical of the I-84 pavement reconstruction project performed in Weber Canyon near Morgan, Utah, were investigated. The laboratory work was based on a full-factorial experimental design, including five RAP contents, five cement contents, and three replicate specimens of each possible treatment. Measurements of unconfined compressive strength (UCS) and final dielectric value in the tube suction test (TST) were used to assess material strength and durability, respectively. These data, together with dry density measurements, were evaluated through an analysis of variance (ANOVA). The results of the ANOVA performed on the UCS data indicate that UCS decreases from 425 to 208 psi as RAP content increases from 0% to 100% and increases from 63 to 564 psi as cement content increases from 0.0% to 2.0%. Similarly, the final dielectric value decreases from 14.9 to 6.1 as RAP c...

The purpose of this research was to investigate the influence of reclaimed asphalt pavement (RAP) on the mechanical properties of recycled base materials typical of northern Utah. Two sources of RAP, two sources of base, and five RAP contents were evaluated in a full-factorial experimental design in which the California bearing ratio (CBR) test, free-free resonant column test, and tube suction test were used to measure strength, stiffness, and moisture susceptibility, respectively. A fixed-effec...

Full-depth reclamation processes are explained as a way to create a good foundation and pavement base. Full-depth reclamation recycles material from deteriorated asphalt pavements and, with cement added, creates a new stabilized base. Then a surface is applied, either hot- mix asphalt or concrete. Recycling cuts costs normally by 25% to 50% compared to removing and replacing old pavement. The article explains which roads are candidates for full-depth recycling with cement, advantages of stabiliz...

The U.S. road management establishment gives as much consideration to aggregate properties as to binder properties. The quality of aggregate used is of tremendous importance, since aggregates are essential in the performance of open-graded friction courses. In addition, skid- resistant aggregates are an important part of highway safety. As demand for high-quality aggregates grows, there are a number of supply issues to consider. For instance, public road agencies put the responsibility for provi...

A recycling project on the Natchez Trace Parkway illustrates a technique using cement as an additive. Because of its nearness to major recreation areas, including an area administered by the National Park Service, crew and machine movements operated under strict rules to reduce disruption to recreational users. The project was a first for the Federal Highway Administration (FHWA) and a pilot for the Mississippi Department of Transportation in the new recycling techniques. Cost-saving efforts red...

The Tube Suction Test (TST) was developed in a cooperative effort between the Finnish National Road Administration and the Texas Transportation Institute for assessing the moisture susceptibility of granular base materials. The moisture susceptibility ranking is based on the mean surface dielectric value of compacted specimens after a 10-day capillary soak in the laboratory, where the Adek Percometer (Trademark) is employed in the test to measure the dielectric values of specimens. Based on prom...

Winn Rock (CaSO4) gravel from a quarry in Winn Parish in north Louisiana was used extensively as a surface course for local parish roads. Stabilization of these roads with Type I portland cement followed by an overlay of asphaltic concrete resulted in heaving. A study was undertaken to investigate the cause or causes of the expansion as well as to identify an alternate means of stabilization. Specimens of representative soil from the affected area were stabilized in the laboratory using various ...

Pavement rehabilitation and reconstruction generates large quantities of reclaimed asphalt pavement (RAP) aggregate, and recycling into new asphalt paving mixtures is the predominant application. RAP acceptance in road bases and subbases has been limited because of the lack of laboratory and field performance data. In the Sultanate of Oman, recycling of pavement materials is not practiced. A previous study conducted at Sultan Qaboos Univ. indicated that RAP-virgin aggregate mixtures could be uti...

Researchers designed a laboratory test sequence to identify the optimum amount of portland type I cement for stabilizing two aggregates, limestone and recycled concrete, typically used in the Houston District. Smectitic compositions identified through mineralogical investigations corresponded with the poor performance of the untreated aggregates in preliminary testing and substantiated the need for stabilization. Samples were subsequently treated with 1.5%, 3.0%, and 4.5% cement and tested for s...

Full-depth reclamation (FDR) is the technique of in-place recycling of the asphalt-bound layer of a pavement along with part of the underlying unbound layer to produce an improved base material. The objective was to develop a mix design system for FDR and evaluate the performance of designed reclaimed materials from the western part of Maine. Mixes were prepared in the laboratory, and samples were compacted with the Superpave® gyratory compactor. The samples were then tested for bulk specific gr...

A simple laboratory test for evaluating unstabilized granular base material is introduced. The test consists of monitoring the capillary rise of moisture within a 300-mm-high cylinder of compacted aggregate. The moisture conditions at the aggregate surface are monitored with a dielectric probe. A graph of surface dielectric versus time is used as the basis for performance classification. The poorest-performing materials are those that rapidly reach saturation and exhibit high surface dielectric ...

Abstract Spectral induced polarization (SIP) and bender element (BE) techniques show a high sensitivity to particle size, particle distribution and content of generated hydration products, which essentially govern the efficiency of ground improvement. In this context, both SIP and BE were integrated on a column setup to monitor the processes of lime and cement stabilization. A 5 mmol/L Na2CO3 solution was injected into the sand-lime mixture to produce CaCO3 precipitation, while deionized water w...

In the highway construction industry especially for pavement base material, cement treated material is a conventional method that had been applied. Other than that, there is various types of base can be used such as cement kiln dust, reclaimed asphalt pavement, fly ash, and mine tailings. The usage of this various material can improve the unconfined compressive strength (UCS) of the base it terms of the strength. It was found that the UCS is the important properties to indicate the durability of...
