The objective of this research is to develop a pavement design procedure that allows calibrating the design variables of asphalt pavements using regionalized conditions, to obtain efficient pavement performance for developing countries with limited resources and data. This study analyzes the roads of the state of Baja California, Mexico; where type structures are determined and the performance grade of the binder used in the manufacture of asphalt concrete is regionalized according to the weather conditions altitude, traffic, and quality of the available materials. In a complementary way, the economic incidence of pavements during its service life is analyzed, projecting the analysis with different pavement structures and damage coefficients. The results show that this approach favors the asphalt pavements that comply with the projected in its service life, reducing maintenance interventions and costs.

This research estimates the amount of emissions of carbon monoxide (CO) caused by waiting times at border ports of access (PAF) of Baja California-California, and the possible implications on the population living in neighboring urban areas.

El presente estudio argumenta que la modernización de la Carretera Federal No. 5 Mexicali-San Felipe ha impactado en el bienestar social de diez localidades aledañas. A pesar de que la obra no ha sido culminada en toda la extensión del tramo carretero, se estiman los Índices de Marginación Urbana (IMU) en su situación ex-ante (2000) y ex -post (2010). Se observa que las dos localidades conectadas directamente con el tramo carretero han disminuido su situación de marginación en forma considerable, al igual que otras cinco  interconectadas a través de la red secundaria. Las tres restantes no se han beneficiado debido a su poca accesibilidad dentro de la red secundaria. Se concluye que la accesibilidad es el factor clave que permite mejorar sus condiciones socioeconómicas a través del tiempo. AbstractThis study argues that the modernization of the Federal Highway No. 5 Mexicali-San Felipe has impacted over social benefits of ten localities. Despite that the works have not been concluded in all the extension of the highway, the Urban Marginal Index are estimated at their ex-before (2000) and ex-post (2010). It is observed that the two localities that connect directly with the road have decreased their marginalized situationconsiderably, as well as the other five localities interconnected through the secondary network. The remaining three has not been benefited because of its poor accessibility within the secondary network. It can be concluded that the accessibility is the key factor that improves their socioeconomic conditions over time.
