Asphalt pavement contractors discus the complete method to properly install a new asphalt surface.
Pavement Types. Basically, all hard surfaced pavement types can be categorized into two groups, flexible and rigid. Flexible pavements are those which are surfaced with bituminous (or asphalt) materials. These can be either in the form of pavement surface treatments (such as a bituminous surface treatment (BST) generally found on lower volume ...
Technical standards, e.g. road profiles, grades, drainage, as well as planning and construction methods are described in numerous textbooks, but are not legally enforced.

The construction industry in a country contributes significantly to the national economy. Developing countries in Asia produce a huge amount of construction waste. Road Construction (RC) projects, which are quite risky, often end up with cost and time overruns. Construction materials account for a major portion of the cost overruns. …

It includes estimates for earth works like excavation, embankment construction and subgrade work. It also provides quantities for sub-base and base course materials as well as bituminous works like tack coat, dense …
The glass fiber-reinforced polymer-modified DBST is basically composed of three materials: (1) aggregates, (2) asphalt emulsion, and (3) glass fiber. Figure 1 shows a diagram of the construction procedure of the modified DBST, which was also applied in the fabrication of the specimens for this study.
The objective of the research is to carry out investment appraisal on road project undertaken using concrete pavement and asphalt pavement and to compare their lifecycle costs and their initial cost of construction. The findings were as follows; the initial cost of the asphalt pavement was cheaper than concrete pavement.
Cost Estimation of any construction works and projects are very necessary to forecast the probable cost that is to be spent for its completion. It is also very helpful to identify the different types of expenditures and cost which are categorized in different subdivisions. This helps to minimize the cost and time of completion as well as maximize the work …
This original subproject, which commenced construction on January 2023, was designed to upgrade the existing laterite road with a length of 1,012 meters to DBST road and it is about 30% of construction (by mid-May 2023).
Our work has introduced a new HE method using deep learning based DBST LCM CLAHE to denoise an image depending on CLAHE's dynamic block size selection method.

The construction of the DBST road with appropriate climate risk reduction measures along sections of the road that are low-lying will result in a road that is durable and with good maintenance it will bring lasting benefits to the local residents.
Road construction continues to hold a high priority among the development priorities of Nepal. The government has the objective of constructing feeder roads to every district headquarters not yet linked by road. To date there has been steady but rather slow progress in reaching this objective. Budget constraints are acute due to large number of …
Road construction requires substantial volumes of materials so reducing the transport distances has a major impact on the final cost of the works. Therefore, design methods are developed with the objective of relying to the extent possible on locally available resources.
Assessing the performance of existing pavement structures, is quite challenging. The repeated triaxial load tests on cylindrical specimens are routinely used to measure the resilient capacity of pavement. The resilient modulus (M_R) testing equipment, is not readily available in an in-situ setup as a result of the complexities of the test …
