Search Construction Cycle 2 (CC-2) Test Strip (PCC) Database
More than 200 sensors were embedded in the test slabs for data collection. The sensors were of two types, static and dynamic. Static sensors were used to monitor temperature and moisture. Moisture sensors existed in the subgrade from CC-1 and were re-used. Experimental vibrating wire strain gauges and resistance crack indicators were also part of the static system. Dynamic sensors measured concrete strains and pavement deflections. Test vehicle operations triggered data retrieval from the dynamic sensors at an increased sampling rate. Sensor data collected during both traffic and non-traffic time periods were processed and stored in a computer database maintained on-site. The database is searchable online using the tools below.
Summary of Daily Traffic Repetitions
The traffic data for flexible and rigid pavement test items are available. Daily and monthly traffic repetitions, as well as current traffic totals, are given for each test item. It is strongly recommended that users consult this table to become familiar with the trafficking history before searching the static and dynamic data.
