Descriptive statistics is the branch of statistics that deals with the quantitative description of the basic features of data collection. Descriptive statistics aim is to rearrange the data in a sequence and at the end summarize the data and represent …
Statistics is a branch of mathematics that deals with the study of various techniques used for the collection, organization, analysis and interpretation of data. After the interpretation of data, a final report is written that is comprised of data, results …
Flexible pavement differ from rigid pavement in terms of load distribution. In flexible pavements load distribution is primarily based on layered system. While, in case of rigid pavements most of the load carries by slab itself and slight load goes to the underlying strata. Structural …
From the word flexible, it is very clear that in this category pavement that come are those that deflects under the applied load. Flexible pavements are very dependent on the underlying layers, these underlying layers ( surface layer, base , …
From the word “rigid”, it is clear those pavements that are of a high strength. Rigid pavements are the laid surfaces that are constructed of high strength concrete on foundations having little resistance against live loads. Rigid pavements provides only …
Pavement is a hard, high strength top finished road surface that separates the underlying well-compacted foundation from the weight of vehicles. Pavement is in between the wheels of vehicles and the foundation of a road. Underlying foundation is mostly a …
Emulsion Emulsions are much more benefit than cutbacks. These are given below; Emulsions are environmental friendly. Emulsions have no effect on environment, because in emulsion there is no such diluent which has negative effect on environment. Emulsions are cheaper than …
Cutbacks are form by the combination of asphalt cement with solvent (kerosene oil, diesel, gasoline etc…). In cutbacks asphalt cements are mixed up with solvents due to the requirement of resultant less viscosity fluid, so that these can be used …
Materials which are being used for bond between different constituents of pavement, and that bond remains intact under different conditions. Binding materials actually increase the resistance between individual elements of mixture and increase its strength against impact loading. There are …
A slope of the secant between two points on the curve is known as secant modulus. Secant modulus is applicable when concrete specimen shows non-linearity or where initial tangent modulus not gives too much required information. It is mostly applied …
