Asphalt Strain Gages

CTLGroup's Asphalt Strain Gages are custom-designed to withstand the high temperatures and compaction loads associated with the construction of asphalt pavements. Full-bridge configuration provides higher signal output and reduces cost because no expensive data acquisition or signal conditioning systems are necessary for bridge completion.

Concrete Strain Gages 

Embedment strain gages are ideal for measuring dynamic strains in concrete pavements. Full-bridge configuration allows for higher bridge excitation and lower long-term drift. CTLGroup also provides economical quarter-bridge sister-bar gages for measurement projects lasting less than one year. Click here to download a PDF Product Bulletin.
