Rut Resistant Asphalt Pavements
The author of this article examines the causes and potential cures of asphalt pavement rutting. He explains that rutting on the asphalt pavement surface commonly is the result of an unstable asphalt mix, heavy vehicle traffic, and high pavement temperatures. He notes that this type of rutting is often observed at intersections, bus stops, freeway off ramps, or under extreme loading situations on airport runways or dock loading facilities. He explains how an engineer can determine if rutting in the asphalt pavement surface is due to distress throughout the entire pavement structure or due to failure in the asphalt layer only. He suggests that asphalt mixes can be designed to resist rutting with the proper selection of materials, good construction practices, and use of appropriate mix design methods. Good compaction practices during construction will improve rut resistance by increasing the interlock of aggregate particles in the mix.
RELATIONSHIP BETWEEN DENSITY AND STABILITY OF ASPHALTIC PAVING MIXTURES
THAT AN INCREASE IN DENSITY OF AN ASPHALTIC PAVING MIXTURE RESULTS TO SOME DEGREE IN AN INCREASE IN STABILITY IS A CONCEPT IN WIDE USE TODAY. WITHIN CERTAIN LIMITS, AND DEPENDING UPON ONE'S DEFINITION OF STABILITY, THIS RELATIONSHIP MAY PROVE TO BE CORRECT. FROM EXPERIENCE, HOWEVER, IT HAS BEEN FOUND THAT DENSIFICATION OF SOME ASPHALTIC MIXTURES IN THE ROAD BY TRAFFIC OVER A PERIOD OF TIME HAS ACTUALLY RESULTED IN A DECREASE OF STABILITY. THERE EXISTS SOME LABORATORY EVIDENCE WHICH SHOWS THE SAME PHENOMENON.
Reading relations: Structures of literary production : a dialectical text/book
Preparing the books to read every day is enjoyable for many people. However, there are still many people who also don't like reading. This is a problem.
