INTRODUCTION: Many entities currently use recycled asphalt pavement (RAP) and other aggregates as base materials, temporary haul roads, and, in the case of RAP, hot mix asphalt construction. 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. OBJECTIVE: The objective of this research was to determine feasibility of cement and fly ash treated RAP and other aggregates as a structural layer for both portland cement concrete and hot mix asphalt pavement systems.
The objective of this study was to determine feasibility of cement and fly ash treated recycled asphalt pavement (RAP) and other aggregates as a structural layer for both portland cement concrete and hot mix asphalt pavement systems. A 610 limestone from Kentucky was used as the reference material. Other materials used in the study include: Mexican 610 limestone, gravel and limestone based RAP, and blended calcium sulfate (BCS). Samples were prepared with three cement and fly ash contents and tested for compression and flexural strength. Length changes specimens were also produced and the resilient modulus was measured.
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.
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.
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.

Field evaluation following laboratory work which suggested that ammonium phosphate-treated fly ash (APFA) may be as much as three times more cost effective than portland cement-treated base courses. Study also determines whether low cost aggregates such as crusher fines or unprocessed sands can be used with APFA.
