Microsurfacing Urban Pavements
A European maintenance technique called microsurfacing can add years to the service life of cracked, ravelled pavements--with minimal interruption to traffic and for less than half the...
Computer Model for Infiltration System Design
This paper describes a personal computer model which was developed to assist in the design and analysis of infiltration systems. The systems included in the model are infiltration basins,...
Uncertain Reasoning in a Pavement Management System
A major objective of a Pavement Management System (PMS) is to assist highway engineers and managers in making consistent and cost effective decisions related to maintenance and rehabilitation...
Global Network Optimization for Pavement Management
In a state-wide pavement management system, the highway network can be divided into a number of road categories based on traffic level and geographical region. Network optimization analysis...
An Artificial Neural Network Approach to Pavement Maintenance Decision Support System
An important component of any Pavement Maintenance Decision Support System (PMDSS) is the condition survey and rating procedures. Data obtained from these procedures are the primary basis...
Pavement Treatment in Ohio Transportation System
This paper presents a modification of the original method in which the concept of fuzzy set theory is applied in the calculation of the PCR. Fuzzy numbers are introduced to represent those...
Integrating Computer Application for Pavement Management: A Case Study
This paper presents a case study of the process through which a relational database management system and stand-alone application programs are developed and integrated to form a comprehensive...
The Control of Settlement Using Geogrids
The applicability of geogrids in reducing settlements has been investigated in the laboratory in two separate studies, in unpaved roads under cycled load applications, and as overlays...
Sheet Flow Resistance of Asphaltic Pavements
A statistical study has been conducted by the authors using 400 points of experimental data taken in the 1970's at Texas A&M for sheet flow runoff during artificial rainfall on...

Chicago Automates Expressway Lanes
Chicago motorists will soon reclaim another rebuilt expressway in October with substantial completion of a $450 million, 7.5 mi portion of I90/94, the John F. Kennedy Expressway. The two...
America's Pavements: World's Longest Bathtubs
Pavements are the most unusual structures designed by civil engineers. Water flows through their tops, bottoms and sides but because pavements are relatively flat, flows out again very...
Pittsburgh Goes International
The size of the new $785 million Pittsburgh International Airport�900 developed acres�is twice the size of the city's Golden Triangle business district but occupies only a...
Integration of a Municipal Pavement Management System with a Geographic Information System
This paper describes the use of a Pavement Management System (PMS), and the integration of the pavement condition data with a Geographic Information System (GIS). In June 1988, the Pavement...
Spreadsheet Pavement Management Systems for Local Roads
Changes in administration and funding levels at the local government level are continuing to illustrate the need for information systems to aid the county engineer or public works director....
Bonded Polyester Concrete Overlays Used in California
Bonded polyester concrete overlays have been very successful in California in restoring and preserving bridge decks from damage by road salts. The polyester concrete system has been employed...
Performance and Serviceability of Composite Floors
Concrete slabs on steel deck are the most common type of floor system in use today. This system of construction is particularly advantageous when ultimate strength design (LRFD) is used....
Recycled Roads
The movement to recycle wastes in highways appears to be gathering momentum nationwide. Rubber from old tires, wood chips, reclaimed asphalt pavement, fly ash, scrap plastic, mining wastes...
Quality Control and Constructability of Slabs on Grade With Expert Systems
Constructability and quality control problems associated with the construction of slabs on grade are many. They vary from problems associated with cracking, scaling, dusting and spalling,...
PDS: An Expert System for Distress Diagnosis of Flexible Pavements in Taiwan
Pavement distress diagnosis requires a significant amount of engineering judgement which is difficult, if not impossible, to be quantified. This is an excellent domain for the development...
