Development of Dynamic Fatigue Failure Criterion
(American Society of Civil Engineers, 1988)When a truck wheel moves on the road, stress pulses develop within the pavement layers. These pulses are primarily functions of load magnitude, tire pressure, and vehicle speed. In this study, dynamic analysis is used to ... -
Role of Advanced Technologies in Transportation Engineering
(American Society of Civil Engineers, 1988)Transportation engineering is a major component of the civil engineering profession. It involves planning, design, construction, maintenance, and operation of transportation facilities. Advanced technologies in the area ... -
Optimized Gravity Models for Commodity Transportation
(American Society of Civil Engineers, 1988)This study is based on a comprehensive commodity flow survey done in Alberta in 1977, which covered the full range of commodity flows by different modes of transportation. The survey data is grouped into specific commodity ... -
Comparison of German to Marston Design Methods
(American Society of Civil Engineers, 1988)In the United States and several other countries around the world, the Marston load theory is commonly used in computing the trench backfill loads on rigid pipes. Germany is using an alternative method developed by ... -
Decorative Concrete Block Pavements
(American Society of Civil Engineers, 1988)Engineers today generally utilize Portland cement concrete and bituminous concrete to construct streets. However, an aesthetically pleasing alternative, brick pavers, does exist. Michigan Avenue in Lansing, Michigan, was ... -
Optimization of Feeder Bus Routes and Bus‐Stop Spacing
(American Society of Civil Engineers, 1988)Existing studies of transit network design deal separately with the problems of determining the optimal route spacing and operating headway, and that of determining the optimal stop spacing. This paper presents an analytic ... -
Alternative Supply Standards for Bus Systems in Major Cities in Korea
(American Society of Civil Engineers, 1988)The current system of supply standards for buses in Korean cities fails to reach the demand for services. Passenger demand varies with route, time of the day, and with location along each route. In order to overcome this ... -
Reliability Model for Pavement Performance
(American Society of Civil Engineers, 1988)A simulation model to calculate the reliability/performance of pavements is developed. The computer program, Reliability Analysis and Performance of Pavements (RAPP‐I), employs Monte Carlo simulation techniques to solve ... -
Analytical Framework for Optimizing Pavement Maintenance
(American Society of Civil Engineers, 1988)The problem of scheduling maintenance for pavements in an optimum fashion has been approached in a variety of ways by researchers and practitioners. However, the Markov decision process has found very limited use despite ... -
Mechanistic Design Concepts for Heavyweight F‐15 Aircraft on Flexible Pavement
(American Society of Civil Engineers, 1988)A new F‐15 aircraft is now the heaviest fighter aircraft in the United States Air Force inventory. A mechanistic design procedure is developed for flexible pavements to accommodate the heavyweight F‐15 loading. The ILLI‐PAVE ... -
Transit Dwell Time Under Complex Fare Structure
(American Society of Civil Engineers, 1988)This paper focuses on the effect on passenger dwell time from a complicated fare structure on a bus transit system. Analysis of data collected from three routes of the Southeastern Michigan Transportation Authority (SEMTA) ... -
Economic Analysis of Rubber‐Modified Asphalt Mixes
(American Society of Civil Engineers, 1988)The Alaska Department of Transportation and Public Facilities (ADOTPF) is presently evaluating the use of recycled rubber in hot mix pavement applications. The benefits of adding rubber to the mix include increased skid ... -
Closure to “<i>Concrete Pavers for Aircraft Pavement Surfaces</i>” by John A. Emery (November, 1986, Vol. 112, No. 6)
(American Society of Civil Engineers, 1988) -
Reliability Analysis of Premium Pavement Design Features
(American Society of Civil Engineers, 1988)This study evaluates the special features of premium design guidelines—features not considered in the AASHO flexible and rigid pavement design procedures. The significance of these features—fifteen in all for four pavement ... -
Impact of Freight Consolidation on Logistics System Performance
(American Society of Civil Engineers, 1988)The effect of recent deregulation of the transportation industry has been to increase the relative costs of small shipments in low‐volume traffic lanes. Freight consolidation has been suggested as an effective way to reduce ... -
Delay Models for Mixed Platoon and Secondary Flows
(American Society of Civil Engineers, 1988)A mathematical model is described for estimating approach delays at pretimed, signalized, coordinated intersections. The delay models incorporate the size of and flow rate within the progression bandwidth. Platoon dispersion ... -
Comparative Assessment of 1985 HCM Delay Model
(American Society of Civil Engineers, 1988)Delay is an important measure of effectiveness in traffic studies; it represents the direct cost of fuel consumption and indirect cost of time loss to motorists. The 1985 Highway Capacity Manual (HCM) used delay as the ... -
Service Life Assessment of Concrete Pipe Culverts
(American Society of Civil Engineers, 1988)The durability and service life of concrete pipe culverts are discussed. The study reported includes the analysis of important enabling and triggering events that have caused or have the potential to cause the deterioration ... -
Energy Dissipation and Limiting Discharge with Orifices
(American Society of Civil Engineers, 1988)Equations and methods are presented to calculate the energy dissipation and the limit of maximum choked flow for orifices and sudden enlargements. A correction factor -
