Data Compression Approach for Long-Term Monitoring of Pavement Structures (2019)
Journal Article

Pavement structures are designed to withstand continuous damage during their design life. Damage starts as soon as the pavement is open to traffic and increases with time. If maintenance activities are not considered in the initial design or consider... Read More about Data Compression Approach for Long-Term Monitoring of Pavement Structures.
