The rapid development of high-performance computing facilities and techniques in recent years has made molecular dynamics (MD) a feasible tool for studying the behaviors of asphalt mixtures under various operating ...
Areca fiber reinforced alkali-activated black cotton soil using class f fly ash and limestone powder for pavements

Chethan, BA; Shankar, AUR [Conference-Full-text]

Alkali activation has gained importance in place of cement treatment in construction due to reduced CO2 emissions. The precursors that are rich in silica, alumina, and calcium can be used for soil stabilization with a ...
Asphalt pavement texture level and distribution uniformity evaluation using three-dimensional method

Dong, S; Han, S [Conference-Full-text]

To supplement the research on the evaluationmethod of asphalt pavement texture, novel three-dimensional (3D) methods are proposed. First, pavement textures were measured in laboratory from asphalt mixture specimens using ...
Assessment of laboratory and field compaction of dense graded aggregate bases (dgab)

Bambarandage, AR; Jayantha, WRAN; Mampearachchi, WK [Conference-Full-text]

Dense Graded Aggregate Base (DGAB) construction is a major contributing component in flexible pavement construction in terms of pavement structural capacity and the project cost. However, the production processes related to ...
Assessment of operating speeds of rehabilitated rural roads with asphalt surfacing

Wijeratne, DDS; Dishan, M; Mampearachchi, WK [Conference-Full-text]

In Sri Lanka, rural roads are not explicitly designed on technical requirements. So far restoration of rural roads went through with mere Construction enhancements and appropriate geometric improvements have not been ...
Assessment of present pavement condition using machine learning techniques

Sharma, M; Kumar, P [Conference-Full-text]

Quantification of present pavement condition in terms of an index term i.e., Pavement Condition Index (PCI) is one of the most important and primary steps while taking decision related to Maintenance and Rehabilitation ...
An assessment of the polishing behaviour of road surfacing aggregates in Sri Lanka

Thenuwara, HV; Jayasuriya, WWC; Pasindu, HR [Conference-Full-text]

Friction capacity between the tire-pavement interface, facilitates sufficient braking force ensuring road user safety. Inadequate skid resistance has been identified as the prominent pavement-related cause of highway ...
Automatic pavement crack rating for network-level pavement management system

Tan, JY; Nguyen, T; Kapilan, S; Nyunt, TT; Lim, YH; Leong, YF [Conference-Full-text]

Cracking is one of the important distresses that can be used to trigger pavement maintenance treatments. Traditional crack rating is commonly based on the Pavement Condition Index (PCI) approach involving time-consuming ...
A brief review: application of recycled polyethylene terephthalate as a modifier for asphalt binder

Zair, MMB; Jakarni, FM; Muniandy, R; Hassim, S; Ansari, AH [Conference-Full-text]

The management of the waste materials produced on the earth is one of the highly substantial environmental issues. Hence, the increasing usage of plastic every year is one of the concerns across the entirety of theworld. ...
Carbon footprint assessment of steel slag asphalt pavement in Singapore

Lol, SS; Subramaniam, SK; Xusheng, H [Conference-Full-text]

Electric Arc Furnace (EAF) Steel Slag is a by-product generated from the steel-making process which is being used as aggregates for the road construction wearing course.Replacement of naturally occurring aggregates with ...
Challenges for the compaction and proving of granular fills and layers in airport pavements

White, G; Anstee, H [Conference-Full-text]

The compaction and proving of granular materials during construction is fundamentally import to airport pavement design practice. This is particularly so in countries that make significant use of granular base courses ...
Chemical properties of modified bitumen incorporating coconut char

Mamat, R; Hainin, MR; Hassan, NA; Warid, MNM; Satar, MKIM; Rahman, NAA [Conference-Full-text]

Agriculture waste have many advantages such as high specific strength and modulus, low density, renewable nature, biodegradability and absence of health hazards. This advantage is good for construction industry because ...
Clogging resistance of high strength pervious concrete

Lee, MG; Wang, YC; Wang, WC; Yatsenko, EA; Wu, SZ [Conference-Full-text]

This clogging resistant study includes high strength pervious concrete (HSP) and normal pervious concrete (NSP). The HSP concrete aims to carry out 28- day strength above 42 MPa and porosity as close to 10% as possible ...
Comparative assessment of cmsdbc and hmsdbc competency

Prakash, G; Suman, SK [Conference-Full-text]

Over ninety percent of the total road network in India, including the airfield pavements, are flexible pavements with black-top surfaces. The construction of wearing and binder courses of a flexible pavement require high ...
A comparative investigation on the effectiveness of awax and a resin based curing compound as an alternate of water curing for concrete pavement slab

Goel, P; Kumar, R [Conference-Full-text]

In this study, the effectiveness of two easily available concrete curing compounds in the Indian construction Industry namely; wax and synthetic resinbased, in comparison with water cured cubes and beams specimens of a ...
Comparison of flexible airfield pavement designs using faarfield v1.42 and apsds 5.0

Chai, G; Bell, P; McNabb, K; Wardle, L; Oh, E [Conference-Full-text]

A case study has been carried out to compare the design of airfield pavements for a major airport using FAARFIELD v1.32 and APSDS 5.0. For the aircraft departure data used in the study, the pavement analysis shows that ...
