The Importance of Understanding Concrete Slab Thickness By Using A Ground Penetrating Radar
Ground penetrating radar is a beneficial tool for determining concrete slab thickness very easily and accurately. Figuring out slab thickness is essential in seeing how concrete pavements may perform over their service life. Be aware that actually a reduction in the thickness of the slab by as little as one inch may halve its service life. Computing the thickness of concrete slabs is furthermore important in figuring out if contractors have complied with the project specifications when making concrete pavements.
GPR is really technology that is already being widely used in many states as part of their pavement evaluation systems, which includes North Carolina, Texas, Florida, Michigan along with Louisiana, as well as in several European nations like the UK, Finland as well as Denmark, with much success. The radar transmits short pulses of radio waves into the concrete and then makes use of the arrival time and strength of the returning echoes to calculate thickness as well as properties including moisture content. Even so, GPR might not end up being able to make accurate measurements if there's not enough contrast between the concrete along with the underlying base.
What are the advantages of using GPR in calculating concrete slab thickness?
1. Thickness data coming from the GPR may be instantly imported into pavement management systems to enable them to determine the remaining life of the concrete pavement and also figure out the appropriate maintenance and repair actions. Radar readings may be changed into graphical representation for easy interpretation or as ASCI file output.
2. Measurements may be done by GPR equipped vehicles along with small disruption to regular traffic because there is no more any need to close down lanes while measurements usually are being taken. Vehicles can cover as much as 200 miles per day of pavement at regular highway speeds. And automatic data collecting considerably reduces the time necessary to complete the survey.
3. The cost of GPR is much more affordable compared with traditional methods of determining slab thickness such as taking core samples. Concerned agencies possess the option of buying their very own equipment along with training personnel to man it or perhaps contracting services from providers, depending on the spending budget available to them for these types of functions.
4. Highway personnel usually are totally safe when taking measurements because they are no more exposed to hazardous situations including high-speed traffic, bad weather or air pollution.
5. GPR has a higher range of accuracy in its measurements of concrete slab thickness. Depending on the type of layer being assessed, you may enjoy precision within range of 3 % to 5 % (for completely new asphalt). But even calculating thick granular base can give results accurate to within range of 8 % to 15 %.
