Quality Control Method for Pile Driving. Quality control criteria for driven piles are developed using the framework of acceptance-sampling analysis based on the statistical data of static and dynamic load tests. The static and dynamic load tests are often carried out for quality control and verification of load-carrying capacity of driven piles.

Jul 06, 2017· Aggregates form the major portion of the pavement structure. Bear stresses occurring on the roads and have to resist wear due to abrasive action of traffic. Aggregates are also used in flexible as well as in rigid pavements. Therefore, the properties of aggregates are of considerable importance to highway. The aggregates to be used in road construction, particularly
The importance of using the right type and quality of aggregates cannot be overemphasized. The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ-ence the concrete's freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates
Quality tasks during operations include quantity surveys, pile driving, pre-pour inspection, deck placement, product evaluation, material review, quality reporting, record keeping, quality audit and corrective action. The attitude of doing things right the first time and the total commitment to quality involves everyone.
The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.
