Pavement Evaluation. Deflection Based Nondestructive Pavement Analyses Introduction This topic will be oriented toward techniques which can be used to interpret nondestructive testing, NDT, data from the Falling Weight Deflectometer, FWD. There are all kinds of NDT data which can be collected on or about pavements but concentration is placed on measured surface deflections. This article is separated into three broad themes: … Read more Deflection Pavement surface deflection measurements are the primary means of evaluating a flexible pavement structure and rigid pavement load transfer. Although other measurements can be made that reflect (to some degree) a pavement’s structural condition, surface deflection is an important pavement evaluation method because the magnitude and shape of pavement deflection is a function of traffic … Read more Dynamic Cone Penetrometer General The Dynamic Cone Penetrometer (DCP) is used to measure the rate of penetration through the various layers of a pavement.

" 27 May 2013. < 24 October 2015 The phrase “pavement maintenance” can mean a lot of things, ranging from simple cleaning or restriping up to fixing severe distresses like potholes and washouts. Maintenance Work and Pavement Life One goal all maintenance activities have in common is extending the life of the pavement. An important aspect for cost-effective maintenance over the pavement life cycle is the selection and timing of maintenance activities. Preventive maintenance when a pavement is still in good condition (green arrow) is significantly less expensive than treatment after pavement deterioration has accelerated (red arrow).
Categories of Pavement Maintenance. Pavement Management Systems. The American Association of State Highway and Transportation Officials (AASHTO) defines pavement management as “…the effective and efficient directing of the various activities involved in providing and sustaining pavements in a condition acceptable to the traveling public at the least life cycle cost (AASHTO, 1985 [1] ).” This concept of providing pavements and maintaining them in acceptable condition is as old as the first pavement. As pavement networks grew slowly in the first half of the twentieth century and then quickly in the 1950s and 1960s, simple procedures or experience that had worked previously was no longer able to manage these burgeoning networks. Instead, a more holistic systems approach was needed. “…a coordinated set of activities, all directed toward achieving the best value possible for the available public funds in providing and operating smooth, safe, and economical pavements.” Pavement Management System Components Pavement condition surveys .
Life-Cycle Cost Analysis - Asset Management - Federal Highway Administration. Life-Cycle Cost. The new APA document covers all the most important concepts, such as net present value, discount rates, salvage value, maintenance costs, and predicted performance life. Download the new document here. Software from the APA is making life easier for engineers who perform life-cycle cost analysis (LCCA) for pavements. The software, available free from the Asphalt Pavement Alliance (APA), uses the principles recommended by the Federal Highway Administration (FHWA) to compare the economics of alternative designs for a given road project. Four Easy Steps to Good LCCA Analysis 1.
While some have argued in favor of a negative discount rate, the time value of money doesn’t work that way. 2. Inputs should come from relevant, historical data on previously bid projects of a comparable scale for a given location. 3. Life-cycle cost analysis should look initial costs and discounted future costs. 4. The APA’s software comes in two versions: LCCA Original and LCCAExpress.
