dc.description.abstract |
Today in each part of the country, road surfacing is done by Asphalt Concrete. With the increase usage of
Asphalt Concrete, the necessity of Quality Management System was arisen. Hence the Quality
Management System for Asphalt Pavement was developed and established in following areas;
1. Plant operation
2. Asphalt Concrete transportation
3. Paving and Compaction
4. On finished Asphalt pavement
To check the quality control on finished pavement, there are many parameters to be considered. One
important parameter is Roughness value on the finished pavement. Different Technical Specifications
provides various devices to quantify the Roughness value. One such method is to measure Roughness
value using the Rolling Straight Edge.
Here the dominant parameter is ups and downs of the road surface. Rolling Straight Edge equipment
was used to count total ups and downs (Bumps) with magnitude of a particular length. A correlation
between International Roughness Index and Rolling Straight Edge measurement has been developed
using statistical analysis software SPSS. Most significant parameters for the roughness were identified
and modifications to the specification were made.
IRI = 1.662 + 0.02X; (X = Summation of the magnitude of the total bumps >=4mm)
A case study on identifying the high roughness sections of a road was made and effects of remedial
measures were analyzed using the developed correlation. |
