Road classification is the orderly grouping of roads into systems according to the type and degree of service they provide to the public.

A road network is composed of various types of roads, each of which performs a particular service in facilitating vehicular travel between points of trip origin and destination, and in providing access to... [Read More]

Also the work done my heavy machinery is of good quality, this is the reason that we find a wide variety of equipments at every construction site. The heavy machines make possible a lot of tasks to be completed safely and more reliably that cannot be carried out manually. However, the equipment always requires a person or two to perform its heavy functions. The construction work carried out by the manifold heavy equipments can be classified into three major categories which are as follows... [Read More]

Marshal test is extensively used in routine test programs for the paving jobs. The stability of the mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 600 °C. The flow is measured as the deformation in units of 0.25 mm between no load and maximum load carried by the specimen during stability test (flow value may also be measured by deformation units of 0.1 mm). This test attempts to get the optimum binder content for the aggregate mix type and traffic intensity. This is the test which helps us to... [Read More]
