Tool for Reduction and Assessment of Chemicals and Other Environmental Impacts (TRACI) Īcidification, Ecotoxicity, Eutrophication, Global Warming Air (excluding and includingīiogenic carbon, separately), Human Health Particulate Air, Human toxicity (cancerous and non-cancerous, (gross and net caloric value, separately) and United States Environmental Protection Agency’s (gross and net caloric value, separately), Primary Energy from Renewable Resources (gross and net caloric value, separately), Primary Energy from Nonrenewable Resources Raw Materials (feedstock energy), Primary Energy Demand from Renewable and Non-renewable Resources Mix and fuels and following local practices in production, mix design, and construction.ĮLCAP computes 18 different impact category values which include Primary Energy Demand used as (UCPRC) to represent local conditions to the extent possible, by using California’s electricity grid The eLCAP data library has been developed based on the California-specific inventories of materialsĪnd mixes, construction equipment and activities, transportation modes, and use-stage impacts withĬonsideration of pavement vehicle interaction and traffic congestion. It is used for new construction and rehabilitation including overlays. This is the official structural analysis program used byĬaltrans (California Department of Transportation) for flexible pavements. ![]() Is a web application for analyzing pavement structural sections using the The installation requiresĬalME: Caltrans Mechanistic-Empirical Structural Analysis Program for Flexible Pavements, v3.0 ![]() ![]() Is a Setup msi file (Pavement ME Traffic Input Setup.msi 9.1 mb). This software is a Microsoft desktop application (32-bit). The traffic files generatedīy this tool can be used directly as input for AASHTOWare's Pavement ME Design software. Weigh-in-Motion (WIM) axle load spectra analysis results. Triple axles) and other inputs (vehicle class distribution, hourly distribution, axles per vehicle class, and annualĪverage daily truck volume) for a project-specific location on the California highway network system, based on the Pavement ME Design Traffic Input (v1.0.0) generates traffic information (axle load distribution for single, tandem, and It does not require a system administrator's permission, unlike the previous version. Is a zip compressed file (RealCostV2.5.6CA.zip, 2.4 Mb). Software is based on a Microsoft Excel Macro function (64-bit). RealCost-CA (version 2.5.6) is a software program to run life cycle cost analysis (LCCA). In addition flexible pavement deteriorates rapidly cracks and potholes are likely to appear due to poor drainage and heavy vehicular traffic.The Pavement Research Center designs, develops and maintains various reseach class software applications. However, the flexible pavement requires maintenance and routine repairs every few years. The initial installation cost of a flexible pavement is quite low which is why this type of pavement is more commonly seen universally. Flexible pavement distributes load over a relatively smaller area of the subgrade beneath. ![]() It transmits load to the subgrade through a combination of layers. The flexible pavement design is based on the load distributing characteristics of a layered system. Flexible Pavement is so named as the pavement surface reflects the total deflection of all subsequent layers due to the traffic load acting upon it. Depending on the temperature at which it is applied, asphalt is categorized as hot mix asphalt (HMA), warm mix asphalt, or cold mix asphalt. Most asphalt surfaces are built on a gravel base, although some 'full depth' asphalt surfaces are built directly on the subgrade. The bituminous material is more often asphalt whose viscous nature allows significant plastic deformation. Flexible pavement is composed of a bituminous material surface course and underlying base and subbase courses.
