Bituminous surface treatment (BST) or chipseal is used mainly on lowtraffic roads, but also as a sealing coat to rejuvenate an asphalt concrete pavement. It generally consists of aggregate spread over a sprayedon asphalt emulsion or cutback asphalt cement. The aggregate is then embedded into the asphalt by rolling it,
posite type (bituminous surface on a cement concrete base) (1). The statistics on the OF PAVEMENTS. New 1kmlong asphalt and cement concrete pavement sections were used that have roughly the same functionality, representing equiv .. Depending on the type and place of recycling asphalt pavements, the most
concrete slab disposal. Uses of RCA. RCA has been successfully used in many paving appliions, including new concrete paving mixtures for single or twolift concrete pavements, HMA pav ing mixtures, bound and unbound sub base appliions (e.g., cementtreated and granular base), drainage layers, fill. Figure 1.
Recycling of old concrete pavement has become an important issue as more concrete pavement reaches the end of its functional and structural life. Currently, economic considerations are the primary thrust for the use of recycled concrete aggregates (RCA) in Portland cement concrete (PCC) pavement. However, as landfill

Pavement Recycling and Full Depth Reclamation (FDR) is a process that utilizes asphalt from deteriorated roads and mixes it with cement to create a stable solid base for resurfacing. This process recycles worn out pavements, pulverizes them, recombines the crushed asphalt with cement and water and then compacts the
Recycled asphalt pavement (RAP) is the removed and/or reprocessed pavement material containing asphalt and aggregate. The use of RAP in asphalt pavement has become a common practice in the construction of new, and reconstruction of old, hot mix asphalt (HMA) pavements. But little research has been done to

Abstract: This paper documents research focused on evaluating the feasibility of using minimally processed reclaimed asphalt pavement (RAP) as aggregate replacement in concrete

Jul 3, 2007 Recycled concrete aggregate (RCA). RCA is granular material manufactured by removing, crushing, and processing hydrauliccement concrete (see paragraph 3b) pavement for reuse with a hydraulic cementing medium to produce fresh paving concrete. The aggregate retained on the 4.75 mm (No.
Potential Pavement. Performance Improvements. • Foundation stability angular, rough texture and secondary cementing action. • Concrete strength partial substitution of RCA for fine aggregate may increase concrete compressive strength. 6

technical knowledge of several asphalt recycling technologies (inplace and plant). ARRA's "Basic Asphalt Recycling Manual" is used as a reference in this course. Course is ready for your agency's training program. T5040.37 Use of Recycled Concrete Pavement as Aggregate in HydraulicCement Concrete Pavement
A sealing coat is then applied on the recycled layer to protect it against traffic during the works, with one or two layers of asphalt concrete later applied to ensure Thus, with cement bound recycling the bearing capacity is substantially increased and, conversely, pavement deflections and subgrade stresses and strains are
