Book Description
Reclaimed asphalt base (RAB) can be used as granular base or sub-base material in all pavement types, including paved and unpaved roadways. The purpose of this laboratory investigation was to find mechanical properties of Class C fly ash stabilized RAB sub-base for flexible pavement design. It is shown that RAB is a good substitute for virgin materials used in pavement construction. The grain size distribution of RAB is found to critically affect the results. The structural layer coefficient for the RAB stabilized base was found with the existing correlation between California bearing ratio (CBR) and Resilient Modulus. This laboratory testing also investigates correlation between CBR and Dynamic Cone penetration (DCP). It was found that a good correlation exists between CBR and DCP for Class C fly ash-stabilized soils and that the correlations are similar to those developed by other researchers, for varieties of soils.

Book Description
Reclaimed asphalt base (RAB) can be used as granular base or sub-base material in all pavement types. For low traffic volume roads, RAB may be stabilized using self-cementing fly ash to produce high quality road base using cold in-place recycling methodology. A demonstration project was completed utilizing this technology. This thesis presents a compilation of the laboratory test results used to characterize the RAB produced in that demonstration project and fly ash-stabilized RAB physical and engineering properties. The construction procedures and quality control guidelines are also described. Also, the field performance of the stabilized road base is discussed based upon the field CBR tests. Finally, Modulus of resilient for road base was found out by using Falling weight deflectometer (FWD) test and the resulting deflection bowls were analyzed using backcalculation program called Modulus 6.0 developed by Texas Transportation Institute and the Texas A & M University (TAMU).

Book Description
Cold recycling is a technically promising and cost effective method for improving distressed asphalt pavements. Unlike hot-mix recycling, cold recycling lacks extensive field and laboratory performance data. There is no widely accepted cold in-place recycling (CIR) mix design and testing standard available. This study attempts to generate useful field and laboratory data on pavements constructed with CIR mix and technique. Two field case studies are conducted. The testing of field cores and laboratory samples from these two field sites is conducted to address the existing and new methods for design and performance testing of CIR mixes in partial depth pavements. The laboratory tests include physical property testing (e.g., moisture content, gradation, air voids, emulsion, and aggregate properties) and performance-related testing (e.g., resistance to deformation, retained strength, rut, and fatigue). Relative performances of the CIR mixes from the two sites are analyzed.
