RISInfluence of Compaction Methods on the Optimum Moisture Content and Performance of Roller Compacted Concrete Pavements
Publisher: American Society of Civil Engineers
Abstract: Despite numerous advantages, there are a few challenges associated with the designing and fabrication of roller compacted concrete pavement (RCCP) specimens—compaction mechanisms employed in the RCCP mix proportioning, ...
Role of Impact and Compression-Based Crushing on the Physical, Chemical, and Morphological Characteristics of Recycled Concrete Aggregates
Publisher: ASCE
Abstract: The main objective of this article is to study the role of the widely adopted crushing techniques, viz., impact and compression, on the physical, chemical, and morphological properties of recycled concrete aggregates (RCA). ...
Zinc Waste as a Substitute for Portland Cement in Roller-Compacted Concrete Pavement Mixes Containing RAP Aggregates
Publisher: ASCE
Abstract: Owing to heavy toxic metal concentration such as copper, lead, zinc, sulfur, cadmium, and chromium, jarosite particles from the zinc industry are considered a hazardous waste material. Proper and safe disposal or converting ...
Mechanical, Microstructural, and Durability Properties of Soil Stabilized with Alkali-Activated Jarofix for Road Applications
Publisher: ASCE
Abstract: In this study, we investigated the feasibility of jarofix [a zinc (Zn) smelter by-product] as a potential geopolymer binder in soil stabilization for road applications. Different combinations of soil–jarofix (SJ) mixtures ...
Suitability Assessment of Alternative Sands for Concrete Pavement Applications
Publisher: ASCE
Abstract: In this investigation, four types of sands as alternatives to river sand, namely, crushed sand (CS), marine sand, fine recycled concrete aggregate (FRCA), and fine reclaimed asphalt pavement (FRAP), were studied for their ...
Laboratory and Field Evaluation of RAP for Cement Concrete Pavements
Publisher: ASCE
Abstract: In the present study, the feasibility of coarse reclaimed asphalt pavement (RAP) for dry lean concrete (DLC) and pavement quality concrete (PQC) mixes is assessed through laboratory and field investigation. Two kinds of ...
Performance Evaluation of Recycled-Concrete Aggregates and Reclaimed-Asphalt Pavements for Foam-Mix Asphalt Mixes
Publisher: ASCE
Abstract: Mechanical foaming of bitumen is a popular technique employed to reduce the viscosity of binder for ensuring coating of aggregates at lower temperature. The potential of this technique is being utilized widely for producing ...
Improving the Properties of RAP-RCCP Mixes by Incorporating Supplementary Cementitious Materials as Part Addition of Portland Cement
Publisher: ASCE
Abstract: Efforts have been made in the recent past to enhance the strength properties of reclaimed asphalt pavement (RAP) concrete via inclusions of supplementary cementitious materials (SCMs), but only some of the durability ...
Laboratory Investigation of Concrete Pavements Containing Fine RAP Aggregates
Publisher: American Society of Civil Engineers
Abstract: Poor affinity of asphalt toward mortar paste has been testified as the primary reason for reducing the reclaimed asphalt pavement (RAP)–inclusive concrete properties, although the effect of dust present in RAP aggregates ...
