Powerful new modules for HIPERPAV II will predict the early-age performance of jointed plain concrete pavement (JPCP) and its performance beyond the first 72 hours and also the early-age performance of continuously reinforced concrete pavements (CRCP).
Although HIPERPAV II is not a structural design tool, it may be used ill the design phase to help the designer identify potential materials-related problems and make appropriate adjustments to the mix or structural design to prevent cracking.
The developers of the software conducted workshops with a beta version of HIPERPAV II in Iowa, Michigan, and Pennsylvania, and then modified the tool based on the feedback.
HIPERPAV enables field personnel to evaluate the cracking potential of concrete pavements based on a given set of circumstances, which may include placement timing, construction procedures, concrete mixture designs, pavement geometry, and environmental factors.
Several State highway agencies, including the California and Indiana departments of transportation, are considering ways to implement HIPERPAV during their design and construction processes to minimize the potential for early-age cracking in their pavements.
With a wide range of applications, HIPERPAV is used during the planning stage to develop specifications for quality control based on the available materials and climatic conditions of the region where the road-way will be constructed.
Healow's satisfaction with the product led him to adopt the use of HIPERPAV on all of his large-scale pavement projects that use portland cement concrete, including major rehabilitation projects on I-10, I-15, I-80, and I-5.
COMET software, recently developed for FHWA as part of HIPERPAV II, is a Microsoft[R] Windows-based adaptation of a powerful technique for selecting mixture proportions based on a number of performance criteria.
HIPERPAV is a Windows(r)-based computer program that provides guidance on the design and construction of concrete pavement.
Using HIPERPAV, engineers can predict and, thus, prevent uncontrolled cracking during the construction phase (the first 72 hours after placement).
The HIPERPAV program has two modules - one for full-depth paving and the other for bonded overlays.
