ASPHALT INSTITUTE PAVEMENT DESIGN SOFTWARE SOFTWARE

This software can be purchased as either a complete package, or customized to include as many modules as applicable to the pavement types to be analyzed.StreetPave is a concrete pavement thickness design software program sold by the American Concrete Pavement Association (ACPA).

ASPHALT INSTITUTE PAVEMENT DESIGN SOFTWARE MANUALS

The software is modular and expandable, easily updated, and comes with complete training manuals and warranty. The software programs make use of data collected from a thorough evaluation of an entire pavement system, which logs the actual surface deflections of each segment of the pavement.

ItР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s a series of software applications designed for the Personal Computer environment. However, it accounts for traffic differently since the applied traffic is converted to Equivalent Single Axle Loads.Р В РІР‚СњР вЂ™Р’В®RIР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s pavement software is comprehensive, user friendly, expandable, and functionally sound. Similar to the program for airfield pavements, this module can calculate the overlay thickness for highway pavements. This is important to account for the variation in the anticipated pavement support condition and/or traffic intensity. One of its capabilities is to divide the year into different seasons.

This is a very powerful computer program capable of utilizing any aircraft loading configuration in conjunction with back-calculated pavement layer moduli values to calculate the overlay thickness required for a given design period. Overlay Design for Asphalt Airfield Pavements Given a slab thickness, strength, and the anticipated load and tire pressure, this module will calculate the induced stresses and deflections in the slab thereby allowing for determination of its structural capacity. This program is capable of predicting the modulus of concrete slab for a given slab thickness, or the concrete slab for a given slab modulus. This module utilizes a closed form solution based on extensive and comprehensive evaluation of concrete slabs using a finite element program. Backcalculation of Pavement Layer Moduli: Concrete Pavement This module utilizes a theoretical representation of the pavement structure in conjunction with the collected FWD data to back-calculate the moduli values of the pavementР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s layers. Backcalculation of Pavement Layer Moduli: Asphalt Pavement This module utilizes the deflections measured at the corner of concrete slabs to determine the presence of voids under the slab. This is important at the Design/Analysis stage to determine the extent of stress reduction on the loaded slab due to load transfer. From these deflections, the load transfer between slabs can be calculated. When testing concrete pavements, the slabs are tested across the joints with one slab loaded and a sensor bridging over to the unloaded slab. The program also has the capability to normalize the back-calculated asphalt concrete layer moduli to any required temperature.

Prediction of mean asphalt layer temperature and normalization of maximum deflection values to a standard temperature of 70Р В РІР‚в„ўР вЂ™Р’В° F are accomplished using the Asphalt Institute methods. This module will perform such a function on the raw FWD data. To compare data between the tested points, the deflection data needs to be normalized to a user specified design/analysis load. Modules available under this package include the following: Load NormalizationР В РІР‚СњР вЂ™Р’Вuring testing, the applied load will vary as a function of the pavement stiffness for a given load mode and drop height.
