Application of level of service facilities for sidewalk assessment

Hewawasam, C; Saparamadu, S [Conference-Abstract]

The model share of pedestrians, in developing cities has the tendency of being very high, as opposed to developed cities. For example, between 25-50% of trips in major Indian cities, and about 50% of all trips in major ...
Bitumen emulsions as a stabilizer for substandard soil

Udayakantha, PMAK; Mampearachchi, WK [Conference-Abstract]

Sri Lankan road construction sector is dealing with an ever depleting construction material problem, specially finding good quality soil is becoming more and more difficult for projects over the past few years. The accelerated ...
Competitive assessment of container port development in Sri Lanka

Kavirathna, CA; Hanaoka, S; Kawasaki, T [Conference-Abstract]

Owing to the strategic location of Sri Lanka with the world maritime networks, Colombo port is developed as a main transshipment hub port, given that majority of containers throughput being represented by transshipment ...
Criteria based funds allocation system for Sabaragamuwa Provincial Road Network

Panagoda, A; Bandara, JMSJ [Conference-Abstract]

Sabaragamuwa Provincial Road Network (PRN) consists of 2625 km length of class C and D roads. Majority of the roads are interconnected through Road Development Authority (RDA) road network. Sabaragamuwa Provincial Council ...
Design of precast concrete cover slab for pedestrian walkways

Athapaththu, CJ; Perera, IMH; Mampearachchi, WK [Conference-Abstract]

Pedestrians need to experience safety, comfort, accessibility, and efficient mobility. Walkways are often needed in rural and suburban areas to provide access to schools, parks, community centers, local businesses, employment ...
Develop material systems for next-generation infrastructure

De Silva, A; Senadeera, S [Conference-Abstract]

The demand for construction materials continues to rise as the infrastructure development spreads. There is a looming crisis for raw materials used in construction running low due to this high demand, and the material-intensive ...
Development of a choice model for school trips

Sannasooriya, I; De Silva, D [Conference-Abstract]

The school bus service has become more of a necessity due to two major reasons: it engages with the most sensitive crowd in the society, and operates at the most crucial time of the day. A high quality bus service is one ...
Development of a personal vehicle type choice model for Sri Lanka

Perera, KR; De Silva, D [Conference-Abstract]

Vehicle ownership is a key determination factor in any country’s economy. In the Sri Lankan context, it has been identified that vehicle ownership rate has expressively increased over the last decade. Apparently, the road ...
Development of service quality index for sustainable bus transport

Sharic, AHS; Bandra, JMSJ [Conference-Abstract]

Sustainable transport is essential for achieving most, if not all, of the proposed Sustainable Development Goals (SDGs). Improvement of public transport service quality is one of the best alternatives to achieve sustainable ...
Effect of mat thickness for the degree of compaction of asphalt pavements

Gunasekara, KKSM; Mampearachchi, WK [Conference-Abstract]

Compaction of the hot mix asphalt (HMA) is a very important process in road construction. The ability of the load bearing greatly depends on the degree of compaction of the hot mix asphalt pavements (Finn, & Epps, 1980). ...
The effect of water to cement (w/c) ratio on workability of internal curing concrete in the development of high strength concrete with required workability and cement content (ICBP)

Bandra, MMHW; Anojan, T; Mampearachchi, WK [Conference-Abstract]

The escalating demand for highways and other related structure development of any country may lead to the introduction of fast and sustainable construction techniques and materials. Internal curing is an emerging technology ...
Evaluation and improvement of toll collection system in Sri Lankan expressways - case study for Colombo-Katunayake Expressway

Kumara, HBNS; De Silva, GLDI [Conference-Abstract]

With the latest development, three expressways were opened to the public in Sri Lanka and the number of users of the expressway network is expected to rise. The pay toll system in the road is based on the traditional method, ...
Evaluation of rheological properties and performance of asphalt binder modified with nano clay

Shantha, YGPB; Mampearachchi, WK; Adikary, SU [Conference-Abstract]

The rheological behaviour of bitumen is very complex and it can vary from purely viscous to elastic, depending on the loading time and the temperature. Bitumen plays a major role in many aspects of road performance. Various ...
Evaluation of roadway-railway level crossings in main line from Colombo to Polgahawela

Ragulan, K; Amarasingha, N [Conference-Abstract]

When a railway line crosses a road or a path at the same level, it is called a Level Crossing (LC). The total length of the railway lines in Sri Lanka is approximately 1930 km (SLR, 2011). 1047 crossings have been reported. ...
Improvement of aggregate packing model of interlocking concrete block pavement (ICBP) mixture using fly ash

Batuwita, IP; Mampearachchi, WK [Conference-Abstract]

Use of concrete paver blocks is becoming increasingly popular. They are used for paving approaches, paths and parking areas, including their application in pre-engineered buildings and pavements. Interlocking Concrete Block ...
iRoads: smartphone-based road condition monitoring

Abeywardana, HMA; Abeywickrama, UMJ; Amarasingha, PT; Kumarasinghe, RPD; Bandara, HMND; Pasindu, HR [Conference-Abstract]

Measuring and monitoring road conditions are essential to ensure public and vehicle safety, prompt maintenance, as well as fuel and time savings. While developed countries use sophisticated devices installed on specialized ...
