Book Description
Reclaimed asphalt pavement (RAP) and granular base materials were collected from stockpiles in six TxDOT districts to evaluate the feasibility of using high RAP content mixes for base course applications. Mixes containing 100%, 75% and 50% RAP treated with Portland cement of 0%, 2%, 4% and 6% were evaluated in a full-factorial laboratory experiment. For mixes of 75% and 50% RAP, both virgin and salvage base materials, when available, were used.

Book Description
Reclaimed asphalt pavement (RAP) and granular base materials were collected throughout Texas to evaluate the properties of RAP and RAP blended with virgin or salvage aggregates for roadway base course application. Mixes containing RAP of 100 %, 75 %, and 50 % and treated with Portland cement of different dosages were utilized in a comprehensive laboratory testing program. The factors that affect the properties of cement-treated RAP mixes are identified and a mix design model based on typical RAP and granular base materials in Texas was proposed. The design model was verified by the data from the initial field trial on actual construction projects. The feasibility of using a modulus-based procedure for quality assurance/quality control during construction is discussed.

Book Description
INTRODUCTION: Many entities currently use recycled asphalt pavement (RAP) and other aggregates as base material, temporary haul roads, and in hot mix asphalt construction. Several states allow the use of RAP combined with cement for stabilized base course under both asphalt and concrete pavements. There is disagreement on how and what properties to test for cement treated RAP (CTRAP) for both asphalt and concrete pavement structures. This project will give the state agency the information needed to properly evaluate CTRAP and other aggregates. OBJECTIVE: The objective of this project is to determine the feasibility of CTRAP, fly ash treated RAP (FTRAP), and cement and fly ash treated aggregates as a structural layer for both Portland cement concrete and hot mix asphalt pavements systems.

Several states currently allow the use of RAP combined with cement for a stabilized base course under both asphalt and concrete pavements. Currently, there is disagreement on what properties are required and how to test the cement and fly ash treated RAP for both asphalt and concrete pavement structures. This project investigated cement and fly ash treated RAP and other materials to determine their suitability for base course construction.

Book Description
Cement-treated base (CTB) is a general term that applies to an mixture of native soils and/or manufactured aggregates with measured amounts of portland cement and water that is compacted and cured to form a strong, durable, frost resistant paving material. Other descriptions such as soil-cement base, cement-treated aggregate base, cement-stabilized base are sometimes used. This document provides a basic guide on the use of cement-treated base (CTB) for pavement applications. This document provides on overview on the design and construction of CTB for both mixed-in-place and central plant mixed operations. A suggested construction specification is also included.
